What is the error? Is it occurring in the header file itself? Or at the #include statement? What are you trying to include, a standard library or a custom header file?

@Segfault is right. You need a toolchain. Sometimes it's included, sometimes it's not. Depends on how and where you download it. Here is the information you need: help.eclipse.org/indigo/…
